One deterministic module has affine ranking function (((long) -1 * y) + x) and consists of 3 locations. One nondeterministic module has affine ranking function (((long) -1 * y) + x) and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 14.4s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 13.7s. Construction of modules took 0.0s. Büchi inclusion checks took 0.5s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 4. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 5 StatesRemovedByMinimization, 3 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [2, 0, 1, 0, 0].
